Answer:
Step-by-step explanation:
Here we subtract g(x)=x+2 from f(x)=3x^2-4
Properly labeled, we get:
(f - g)(x) = 3x^2-4 - (x+2) (Use of parentheses is essential here.)
or
(f - g)(x) = 3x^2 - x - 2

Since the triangle is a right triangle, we can use SOH CAH TOA to find ?. 10 is OPPOSITE to ? and 21 is HYPOTENUSE to ?, so we can use SIN to find ?.
SIN(?) = 10/21
? = ARCSIN(10/21)
? = 28.437
